Mmmmm ...
ADA (usually) require any new pilots hired to be IFR rated for the licence issue.
It is not (?) possible to get a 'new' IR in Abu Dhabi .... ADA usually require prospective pilots to also have an ATPL H for initial licence conversion as it is not possible to upgrade a converted CPL to an ATPL without having to do the 'complete' ATPL exam' set to then upgrade after the initial licence issue.
ADA machinery is excellent ... IFR capability is basically to cover regulatory requirements ... the only really 'BAD' Wx happens in the mid winter storm season ... other than that its poor vis due dust sand etc etc ... BUT you do need to be capable and able ... the environ can bite !!
Good luck
